Fix 2. Use Disk Utility to Format and Encrypt Hard Drive on Mac

Another solution you can opt to encrypt the hard drive on your Mac is Mac Disk Utility. Using this tool, users can password-protect a particular storage device. If the storage device is internal, you must type the password to access the information. External devices need to be connected to the system, and a password must be entered for data access.

It is vital to know that if you want to use Disk Utility to encrypt the device, you will need to erase it. For that, copying the crucial information to another device is the ideal solution. Now, you can move ahead with the encryption.

Another thing one needs to know is that Disk Utility supports three distinct file system formats. These are:

  • ExFAT and MS-DOS (FAT) for file systems that are Windows-compatible.
  • Mac OS Extended for file systems with macOS 10.12 or earlier.
  • Apple File System (APFS) for file systems with macOS 10.13 or later.

Here are the steps you need to follow:

Step 1. Go to the Disk Utility app on the Mac or boot Mac into Disk Utility.

Step 2. From the sidebar, choose the storage device you wish to encrypt from the sidebar.

Step 3. Now, select the "Erase" button present in the toolbar.

Step 4. Type the name you want for the volume. Go to the Scheme pop-up menu. Now, select "GUID Partition Map".

Step 5. Go to the Format pop-up menu.

Step 6. You will need to choose the type of system format you want. Please enter the password and verify it. Click "Choose".

Step 7. Select Erase button. Click "Done."

Note: Sometimes, you can encounter the Security Options after the password step. Here, you can determine the number of times one can write over the data erased. To confirm the action, select "OK." Remember that the Secure erase options are unavailable for all storage devices. If the Security Options button is not present, you cannot use the Disk Utility to implement secure erase on the device.
